  • GIF image, JPEG image, flash animation, and moving image are compressed and transmitted using a compression method in order to reduce the volume of data transmission. Accordingly, when the video image which has been compressed and transmitted using such a compression method is restored, distortion such as blocking artifacts or ringing artifacts may occur. Accordingly, condition information to distinguish elements which require image post-processing due to such distortion from elements which do not require image post-processing from among elements constituting the contents may be set.

  • the image post-processor may classify the GIF image, the JPEG image, the flash animation and the video image as the first group and classify the graphic rendering and the text as the second group. If the first and second groups are classified, the image post-processor may determine the image post-processing method to post-process the image of each element of the first group based on the predetermined image post-processing method for each element.

  • the display apparatus such as the smart phone or the smart TV may perform the rendering of the elements which are post-processed differently by the image post-processor, and display the contents on the screen.
  • a picture such as a web page displayed on a screen may be made up of a number of elements which form the displayed contents.
  • these elements may be individually, differently post-processed based on individual attributes of the respective element.
  • the elements may also be split into a number of groups such that each group has its own respective post processing. It is possible that post-processing may be omitted for some individual members/elements of contents and/or for some groups.

Abstract

La présente invention se rapporte : à un dispositif d'affichage adapté pour exécuter un post-traitement sur l'image du contenu ; à un dispositif de post-traitement de l'image ; et à un procédé adapté pour exécuter un post-traitement sur l'image du contenu. Le dispositif d'affichage selon l'invention comprend : un module de communication qui communique avec un serveur ; un module d'affichage qui affiche un contenu reçu du serveur ; et un contrôleur qui détermine un procédé pour l'exécution d'un post-traitement sur l'image, pour des éléments du contenu, sur la base de données source du contenu et de données de conditions prédéterminées. D'autre part, le contrôleur commande l'exécution d'un rendu sur les éléments qui sont post-traités conformément au procédé pour l'exécution d'un post-traitement sur l'image ; et il commande au module d'affichage d'afficher le contenu généré après que le rendu a été exécuté. De cette manière, le dispositif d'affichage selon l'invention peut mettre en œuvre un post-traitement d'image, de façon sélective, pour les éléments du contenu.
